i and 4, forming foundation of the boot.

The specific number` of layersimay be changed.the machinebeing adaptable for manufacturingbootsofa less number of plies by disconnecting one of the. fabric rolls, or alterable into laying up, algreater number of -plies bygadding othenunits, fas will be readily understood..V

Between two of the-plies@ referablythe second and thirdplies,` are p aced two narrow strips of rubberized fabric 5 `along the edges of the boot. Centrally' abovethelast fabric ply is placeda narrow strip of cushl ion rubber 6 and above this is"placed a thicker and wider centrally arranged stripA of more heavily compounded rubber 7. V Above this isplaceda thin layer of rubber 8 covering the whole area of the-boot. The boot in the form shown4 inFig.` 10 is sublsequently 'cured in any well known manner, and suitable securing means 4are applied-to "the ed devices. M

The machine comprises 4a number-oflegs- .10 suitably braced as ut'll.` `and carrying fhorizontal side barsv 12, spaced by the rods 12',` which support the rolls of -fabric and rubber and the pressnreand assembling orm 13 which supports the ldriving "l anism. r At the front of the machine on *the side railsl 1-2 are supported a pair .of standhrds 14 provided wlth notches 151 supporting a reel 16 which furnishes the'irst layer of fabric 2. A liner. take off vroll 17` is sup" ported above the roll 1 6 asY is customary.

. A similar pair vof. uprightsl support' the roll`191from which is obtained the second plv of fabric 3,the roll being provided with il." ie'rvt'ewind roll 20x, On'the lower-part ofthe standard 18 is carried a roller21 prof- 4vided with guiding flanges-22 which center the'fabric 2. Slghtlyahead of the roll 19 there .is Vcarried in the side rails 12 a platen oll: 23, abovel which is arranged a' pair of slotfe standards 24 inv which is a pressure roller' 26' mounted for 'verticalV adjustment Vby Vset screws 25, between which rollers the two fabric layers 2 and 3 are passed and squeezed together. Before passing,r between the rollers 23 and 26,?the fabric 3 beneath a guide roller 27 'similar to the guide roller 21.

ges in the form of hooks or lacing'.

passes liti Un the end of the hed of the clicking muchine is an intermittent feed device which receives the compound strip from the layingr machine and feeds it into the, clickcr. The feeding device is designated by the numeral 84 and comprises a pair of adjustable rolls S5 supported in bracketsV 8G from the bed of the clicking machine. A guide roll 87 is carried in the brackets 86 and suports the strip which normally hangs in a lim u beyond thc cnd of thc laying machine. ne ofthe rolls $5 is intermittently driven a distance sullicicnt to advance the strip of laminated material for a new cut` b v means of e. sprocket chain "iii which derives motion from a sprocket wheel SS! mounted on u shaft 90 in a hraclict 91 risiuglf from the bed i3. A pinion U2 is carried on shaft im and meshes with :l ,freu r 93 on n sha1 ft 94 also Asupported in the hruclcct ill. The geur fill is rotated intermittently by a ratchet wliecl 95 on the shaft 9J.. cooperating with a puwl 96 on a lever 97 which is rocked hv a link 9d connected to a crank 99. 'l`hc crank 9) is adjustable in an)` well known manner to vary the amount of advance given to the fabric. The crank iii) is attached to a shaft IDO carried in a bracket 101 on the platform 13, the forward end of the shaft carrying a bevel pinion i02 in mesh with a licvel pinion 103 on a` longitudinal shaft 104 carried in two brackets 105, Fcailiered on the shaft 104 is a friction wheel 10H which is maintained in contact with the rear face of thc disk by the Springr 66. The friction whccl is: arranged to he adjusted across the face of the disk byv a lever 107 pivoted ut i051, so that the Speed of the cutting mechanism may hc adjusted with relation to the .speed ol: the `lavinlgx part of the machine. The free cud of the lever 1i 7 is miroir-d to a rod 10i?. the other end of which is pivotulijfconnected to a screw threaded pin 110, received in a hand wheel 111. supporti-i on a har i12 evtcndingY between ille rear pair of legs l0.

The clicicr operating rod 93 is pivotcd to n lever 113 provided with a piu 114 received in a. bearing' IE5 ou thc upper end of the. standard 101. Below the pin 114. the lever is extended lo carry :i roller iid which reiste. ou u cum suri'acc 11T formed on thc cud of the @hait INH4 liv the construction shown. the movement ol" thc l'uluif' vstrip und ille operation of thc clicking machine may bo alternated. liv liu iifiilirdiiicrit ol the friction wheel 10G. the .speed ol' thc luyin;r and cutting instrumentalitics nmy bc adjusted` und hy thc adjustment of4 the throw of flic crank fifi. thc amount of advance of' the fubric strip may he adjusted indepcndcntlv to provide for different sine dies in the clicking machine.

The nun'ibcr and positioning of the several ,timed relation to supply rolls may be varied without altering the. invention, the type of fabric laying mechanism may be changed and other forms of cutting or dieing;r out mechanism may be Hihsiitutcd for that shown. Other changes and modifications may be made within the scope oi' the invention to which I consider niyscll entitled Within the fair limits of the claims appended hereto.

claim:

l. In a machine of the 'character described, the combination of means for formin c0ntinuously n' strip of laminated material an intermittently;r actuated die press for cutting articles from said strip, feeding means located between the formin means and the dic press. un adjustable driving connection from said forming mechanism to Said die press und feeding means. and an independent adjusting device for governing the action of said feedingr means.

A tire hoot building machine having, in combination` a series of supply holders, means for forming a continuous strip composed of a plurality of layers from said holders` means for continuously actuating said Formingv means, an intermittently actuated die press for cutting tire boots from said continuous strip, means operable in timed relation to said cutting means for feeding said continuons strip to the cutting means, and means for relatively adjusting thc speeds at which the feeding and cutting means operate.

3. A tire boot building machine having, in combination, a series of supply holders, iucuns for forming a continuous strip composed of a plurality of layers from said holders. means for continuously actuating' said forming means, an intermittently actuatcd die presstor cutting tire boots from said continuous strip` meansoperahlc in said cutting means for feeding said continuous strip to the cutting' means, and means for adjustinf.r the speedsv at which thc feeding und cutting' means operato.

4. A tire boot building machine having', in combination, a series of supply holders, means AFor forming n continuous strip composed of a plurality of layers from said holders. an intermittently actuated means for continuously actuating lsaid forming means. die press for cutting,r tire boots from said continuous strip. means for alternatel feeding the strip and operating the cutting;` means, means for varying the s eed of saidV forming and cutting` means in ependently. and means for adjusting the amount of feed of the continuous strip independently of the operation of the cutting' means.' ,i
